Two modes in one app
Switch between audio conversion (M4A, FLAC, WAV, OGG, AAC, MP3, WMA, Opus) and video audio extraction (MP4, MOV, AVI, MKV, WebM) without opening a second tool.
BatchDrop Audio · Windows desktop app
Convert and extract audio on your PC.
BatchDrop Audio converts audio files between MP3, WAV, and FLAC, and pulls audio tracks out of video files — entirely offline. Drop files, pick a format, and keep the originals untouched.
Offline by default
All conversion runs locally using an FFmpeg engine. No files leave the machine, no cloud queue, no account required.
Format control
Choose MP3, WAV, or FLAC output. For MP3, set bitrate from 128k to 320k and sample rate independently per job.
From any audio format to the one you need.
Two straightforward workflows: convert between audio formats, or extract an audio track from a video file. No timeline editor, no project files.
Pick a mode
Choose Convert for audio-to-audio jobs (M4A, WAV, OGG, WMA → MP3, WAV, FLAC), or Extract to pull audio out of MP4, MOV, MKV, and other video files.
Drop files and set output options
Add individual files or a folder. Set output format, MP3 bitrate (128k–320k), and sample rate. Defaults cover most jobs.
Convert locally
Converted files land in a converted subfolder. Originals are never touched.
